Square Root of 100000

Professor Greenline Explaining Math Concepts

If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in the field of vehicle design, finance, etc. Here, we will discuss the square root of 100000.

What is the Square Root of 100000?

The square root is the inverse of the square of a number. 100000 is not a perfect square. The square root of 100000 is expressed in both radical and exponential form. In the radical form, it is expressed as √100000, whereas (100000)^(1/2) in the exponential form. √100000 = 316.227766, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 100000

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where long-division method and approximation method are used. Let us now learn the following methods:

 

  • Prime factorization method
  • Long division method
  • Approximation method
Professor Greenline from BrightChamps

Square Root of 100000 by Prime Factorization Method

The product of prime factors is the Prime factorization of a number. Now let us look at how 100000 is broken down into its prime factors:

 

Step 1: Finding the prime factors of 100000 Breaking it down, we get 2 x 2 x 2 x 2 x 2 x 5 x 5 x 5 x 5: 2^5 x 5^4

 

Step 2: Now that we have found the prime factors of 100000, the second step is to make pairs of those prime factors.

 

Since 100000 is not a perfect square, calculating its square root using prime factorization directly is not feasible.

Professor Greenline from BrightChamps

Square Root of 100000 by Long Division Method

The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.

 

Step 1: To begin with, we need to group the numbers from right to left. In the case of 100000, we need to group it as 00, 00, and 10.

 

Step 2: Now we need to find n whose square is less than or equal to 10. We can say n is ‘3’ because 3 × 3 = 9, which is less than 10. Now the quotient is 3, and after subtracting 9 from 10, the remainder is 1.

 

Step 3: Bring down the next pair of digits (00) to the right of the remainder, making it 100.

 

Step 4: The new divisor will be the sum of the old divisor and the quotient, which is 6 (3 + 3). Now we need to find n such that 6n × n ≤ 100.

 

Step 5: Let n be 1, then 61 × 1 = 61, and subtract 61 from 100 to get 39.

 

Step 6: Bring down the next pair of digits (00) to make it 3900.

 

Step 7: The new divisor is 62 (61 + 1), and we need to find n such that 62n × n ≤ 3900.

 

Step 8: Let n be 6, then 626 × 6 = 3756, and subtract 3756 from 3900 to get 144.

 

Step 9: Add a decimal point and bring down two zeros, making it 14400.

 

Step 10: Continue this process until you reach the desired decimal places.

 

So the square root of √100000 is approximately 316.2277.

Square Root of 100000 by Approximation Method

The approximation method is another method for finding square roots; it is an easy method to find the square root of a given number. Now let us learn how to find the square root of 100000 using the approximation method.

 

Step 1: Now we have to find the closest perfect square of √100000. The smallest perfect square less than 100000 is 96100 (310^2), and the largest perfect square greater than 100000 is 102400 (320^2). √100000 falls somewhere between 310 and 320.

 

Step 2: Now we need to estimate the value between these two perfect squares. We can see that 100000 is closer to 102400 than it is to 96100, so a value closer to 316 is reasonable.

 

Step 3: Using the approximation, we find the square root of 100000 to be approximately 316.2277.

Forgetting about the negative square root

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It is important to make students aware that a number has both positive and negative square roots. However, we generally consider only the principal (positive) square root in practical applications.

For example, √10000 = 100, but there is also -100, which should not be forgotten.

Square Root of 100000 Examples

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

Can you help Max find the length of a side of a square field if its area is 100000 square meters?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The length of a side of the square field is approximately 316.23 meters.

Explanation

The area of the square = side^2,

 If the area is 100000 square meters, then the side length = √100000 ≈ 316.23 meters.

Problem 2

A square-shaped building measuring 100000 square feet is built; if each of the sides is √100000, what will be the square feet of half of the building?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

50000 square feet

Explanation

We can just divide the given area by 2 as the building is square-shaped.

Dividing 100000 by 2 gives us 50000.

So half of the building measures 50000 square feet.

Problem 3

Calculate √100000 x 5.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

1581.14

Explanation

The first step is to find the square root of 100000, which is approximately 316.23.

The second step is to multiply 316.23 by 5.

So 316.23 x 5 = 1581.14.

Problem 4

What will be the square root of (100000 + 2400)?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The square root is approximately 320.

Explanation

To find the square root, we need to find the sum of (100000 + 2400).

100000 + 2400 = 102400, and then √102400 = 320.

Therefore, the square root of (100000 + 2400) is ±320.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √100000 units and the width ‘w’ is 50 units.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

We find the perimeter of the rectangle as approximately 732.46 units.

Explanation

Perimeter of the rectangle = 2 × (length + width)

Perimeter = 2 × (√100000 + 50)

= 2 × (316.23 + 50)

= 2 × 366.23

= 732.46 units.
